The ultimate lightweight detector is as effective on dry land as it is in the water (up to 32 feet.) The one-button operation makes the IP68 a breeze to use, and the 5-minute auto-shutdown saves you loads of battery time.

The one-button system immediately reconfigures your location and target, so you don’t spend time being distracted by other nearby targets. The LED offers four alert levels and is precise enough to target coins, jewelry, and old silver in multiple environments.

The IP68’s  360° area of detection allows for rapid target location precise enough to find metal screws, thumbtacks, or tiny jewelry pieces such as earrings.

The IP68 even comes equipped with a powerful light beam that can illuminate areas underwater with low visibility. The detectors signal through a colored light system and emit a white beam when it has targeted metal.

“Wasn’t sure what the quality would be like buying from Amazon. But after some research, I chose this one and I’m really happy I did. I like the light on the front that changes colors when you get closer to the item. So helpful. It also has a LED type light underneath which makes it very handy in low light situations.”

If you don’t like having to wear hot and bulky headphones when you are out and about, the IP68 alerts you through light and vibration so you may swim and search freely without worrying about whether your headphones are waterproof or not.

With a weight of only 9 oz (255 grams), this is the most versatile and portable detector you will find on the market, and the best thing is you can simply fit it into your belt with no boxes or wires or cumbersome extensions.

Pros & Cons

  • Simple to use and ready to use straight out of the box
  • Fully waterproof
  • Roughly 10cm detection range is perfect for the price
  • The 4-level indicator makes it easy to tell how deep something is
  • Includes a handy belt holster
  • Some may find the simplicity a little off putting


  • FULLY WATERPROOF UP TO 32 FEET UNDERWATER. Take the pointer below the surface of lakes, rivers, ponds, and oceans to locate historic wrecks other searchers can’t find. Other leading detectors only go down 13 feet and cannot be fully immersed in water. This being fully submersible 32 feet depth gives you a big advantage.
  • 360° AREA OF DETECTION. This very sensitive 360-degree pinpointer can precisely locate the target rapidly and accurately and also find metal screws, thumbtacks, and even lost jewelry around your home. Avoid lots of unnecessary digging. Spare your time indoors & outdoors for a memorable treasure hunting!
  • ONE BUTTON EASE OF USE. One Button Operation makes this pinpointer very easy to use. It’s suitable for any age kids to adults. 5 Minute Automatic Shutdown saves battery power for extended life that never lets you down. 4-level LED lets you accurately pinpoint objects in all environments.

  • A PERFECT GIFT FOR KIDS & Friends. This pinpointer metal detector is a perfect Christmas gift for your friends and family numbers who love outdoor adventure. With a compact size, it’s also perfect for kids to reignite their sense of adventure with the great outdoors by giving them the gift of a metal detector pinpointer.


DR.ÖTEK Waterproof Pinpointer Review


DR.ÖTEK IP68 Waterproof Metal Detector Pinpointer, Fully Waterproof Pinpointer to 32 Feet Underwater for Treasure Hunting, LED Indicators & Vibration, Top Metal Detector Accessory for Adults, Kids
On the surface the Dr Otek MT6 Pinpointer appears too simple. But to honest with you, it's affordable and just works. While the lack of an audible speaker maybe a concern for some, this is completely understandable as it helps maintain its waterproof quality. Instead, the innovative 4-level LED is good enough to let you detect how far down something is and it makes digging so much easier. This allows you to waste less time, less risk of damaging the item and you can move to the next spot a little sooner.

Once again we have saved the best till last. The update Garrett AT Pro has the impressive features that have made this detector such a great all-terrain machine. And on top of that, it is also waterproof to 10 feet or 3 meters.

So if you are after a submersible detector that won’t break the bank then you won’t go wrong with this one. You will need to buy separate headphones though, as the ones that come with it are not waterproof.

The all-new ground balance feature of this machine helps fine-tune the metal detector to the soil type and condition you are detecting in. In lay-mans terms, it reduces the false signals and “chatter” from the machine and increases its accuracy.

This true all-rounder, can not only be used in freshwater but also in saltwater too. So it is right at home on the beach as it is inland. In fact, this versatile detector is a jack of all trades. A huge advantage is of course its underwater abilities, making it a very popular choice among the growing band of detectorists, who want to search those places beneath the surface of the water.

“An awesome detector! I’m relatively new to metal detecting, but the assembly and instructions are very easy to understand. Garrett also has a load of YouTube videos that were really helpful as well. I was able to find things my first time out. I would highly recommend this product.”

The AT Pro features advanced audio modes. This allows the user to hear the subtle changes in a target’s response. This added feature helps the user better judge a target’s size, shape, and depth and has the added benefit of a much faster recovery time when detecting adjacent targets.

 At just over 3 lbs, the AT Pro is easy to swing and has a great balanced feel to it. And the six search patterns available in the 2 search modes, provides the user with a very good span of possibilities.

Garrett AT Pro Test Run


Garrett at Pro Metal Detector, Multi-Colour, One Size
Of all the detectors in this review, the Garrett AT Pro seems to have it all. Easy to use yet sophisticated enough for the more advanced detectorist out there. It give the user all the necessary information they need although it may take a while to understand the different signals from what lies under the coil.
